Tips
To obtain a perfect zabaione, pay attention to the temperature of the water: if it’s too high it will thicken the cream too much.
Trivia
According to tradition, zabaione was accidentally invented in the 1500s by Captain Baglioni, while he was camped near Reggio Emilia. Because he had only eggs, sugar and wine at his disposal, he mixed these ingredients together and gave the resulting drink to his soldiers instead of the usual soup. The soldiers were enthusiastic, and the drink was called Zabaione (or Zabaglione), from the name of its inventor, Captain Baglioni.
